I am not sure where you have done your learning on this subject, but of course Black Holes do not "go dormant"...any more than the Earth, as a celestial object, turns on and off in some way. It is what it is...on an on-going basis. And, certainly, the gravitational effects of a Black Hole are "always on" as well.

Actually according to the current data, yes they do. The the usage of the word dormant is usually applied to a non feeding black hole. Even a super massive black hole's gravitational effect can be balanced out.
No matter=no feeding=no growth=dormant.
The closest black holes yet discovered are several thousand light-years away. They are so far that they have no effect on Earth or its environment.
